This was partially addressed in another question, International tax on digital products for a US company , however, I'm still unclear as to what I need to do if the UK removes this threshold next month. Basically I'm selling software for download only, from California with a California LLC. Do I need to be VAT registered - most of my customers are in the UK - but I doubt sales will top the current threshold value.
I understand being UK-registered would cover EU member states too. But what about the rest of the world? How on earth do I keep track of all the sales taxes around the world? I'd rather not go down the route of Digital River or other online sales agents unless I have to. Currently I use Hikashop and Paypal for my website (for other reasons - I haven't started selling yet).
Thanks.
